This Amendment No. 5 (this “Amendment”) amends and supplements the Schedule 13D (the “Original 13D”) filed with the Securities and Exchange Commission (the “Commission”) on June 20, 2008 by AT&T Inc. (“AT&T”) and AT&T International, Inc. (“AT&T”), and, together with AT&T, the “Reporting Persons”), as amended and supplemented through Amendment No. 4 (“Amendment No. 4”) thereto, filed with the Commission on February 28, 2011 ( as so amended, the “Schedule 13D”). Capitalized terms used but not otherwise defined in this Amendment have the meanings ascribed to such terms in the Original 13D. Information about Carso Global Telecom, S.A.B. de C.V. (“CGT”) is based in part on that Schedule 13D filed on behalf of Carlos Slim Helú, his family, and certain related trusts on February 6, 1998, as amended and supplemented through Amendment No. 46, filed on February 28, 2011, thereto (the “Slim 13D”) and the Form 20-F filed by the Issuer on May 11, 2011 (the “20-F”). The Reporting Persons are filing this Amendment because they intend to tender their shares of the Issuer as further described herein. Except as expressly amended and supplemented by this Amendment, the Schedule 13D is not amended or supplemented in any respect.

Item 2.	Identity and Background.
Item 2 of the Schedule 13D is hereby amended and supplemented as follows: (c) The name and principal occupation of each executive officer and director of AT&T and AT&TI are set forth in Exhibit I hereto and incorporated herein by reference. The principal business address for the named individuals on Exhibit I is 208 S. Akard St., Dallas, Texas, 75202, USA. Exhibit I amends and replaces the previously filed Exhibit I (filed as an Exhibit to Amendment No. 2 to the Schedule 13D) in the entirety. (f) Each executive officer and director of the Reporting Persons is a citizen of the United States other than Mr. Chico Pardo, who is a citizen of Mexico.

Item 4.	Purpose of Transaction
Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following language to the end of the third paragraph thereof: On August 1, 2011, Amèrica Mòvil, S.A.B. de C.V. (“AMX”) announced that its Board of Directors approved a tender offer for all of the outstanding shares of capital stock of all classes of the Issuer that are not already owned, directly or indirectly, by AMX, including those shares that are represented by American Depositary Shares. AMX announced that the purchase price will be $10.50 Mexican pesos per share payable in cash. As of the date of this Amendment the Reporting Persons intend, if the Offer is launched, to tender all of their shares in the Issuer in the Offer. The Reporting Persons reserve the right to change their intention regarding the tender of their shares in the Offer.

Item 5.	Interest in Securities of the Issuer.
Item 5 of the Schedule 13D is hereby amended and supplemented as follows. (The following disclosure regarding securities which to the knowledge of the Reporting Persons are beneficially owned by CGT is based on the information contained in Amendment No. 46 to the Slim 13D.) (a) Neither AT&T nor AT&TI have sold any shares of the Issuer since the filing of Amendment No. 4. The percentage of L Shares (including L Shares ADS) of the Issuer beneficially owned by each of AT&T and AT&TI are amended to be increased from 13.36% to 13.45% since the filing of Amendment No. 4. The percentage of A Shares (including A Shares ADS) of the Issuer, which, to the knowledge of the Reporting Persons are beneficially owned by CGT is amended to be increased from 24.08% to 24.85% since the filing of Amendment No. 4. The number and percentage of L Shares (including L Shares ADS) of the Issuer, which, to the knowledge of the Reporting Persons, are beneficially owned by CGT are amended to be increased from 9,137,672,310 to 9,896,094,727 and increased from 64.33% to 69.98%, respectively, since the filing of Amendment No. 4.
